Eminyakeni edlule, omunye wemisebenzi lapho ubuya eholidini, ubenosuku lokuzalwa, noma ubungasekupheleni kukaKhisimusi bekuwukuya esitolo sokuthwebula izithombe ukuyokwakha izithombe bese ubona ukuthi ziphelele kanjani. Eziningi zazo zakhishelwa kusayizi ojwayelekile, okungukuthi, zonke zilingana. Kepha nabanye obukade ukhetha osayizi abahlukahlukene bezithombe ukuwagqamisa, kahle ngoba ubuzowabeka, uwalengise njengomdwebo, njll.
Manje lokhu kusenziwa, yize singasanciki kumakhamera wefilimu, kepha asedijithali, futhi nefomethi yokuthuthuka nosayizi wezithombe kwehlukile. Ngabe ufuna ukwazi ukuthi malini? Ungaphuthelwa esikhuluma ngakho ngokulandelayo.
Amafomethi entuthuko, mangaki akhona?
Into yokuqala okufanele uyazi ngayo amafomethi wokuthuthukisa isithombe ukuthi kunezinhlobo eziningi ezahlukahlukene, futhi ezahlukahlukene. Lokhu kuhlobene kakhulu namafomethi wesithombe sephepha, noma okufana nakho, ubukhulu bezithombe. Ngakho-ke, okuveziwe ongakuthola yile:
Ifomethi yendabuko
Ihambisana nesilinganiso esingu-3/2, esaziwa ngokuthi izithombe zesiliva. Kulokhu, lesi silinganiso esingu-3/2 sihumusha njengobubanzi be-negative obuyizingxenye ezimbili kwezintathu zobude bazo.
Kungani kuthiwa kungokwesiko? Yebo, ngoba iyona esetshenziswa kakhulu. Yize okwesikhashana manje, nangobuchwepheshe obusha, bambalwa futhi bambalwa abazama ukuthuthukisa izithombe benza kuselula yabo, futhi bakhetha ukubagcina bekuyo, noma bayidlulisele kukhompyutha, futhi babone kuyo.
Abanye, abakwenzayo ukusebenzisa amadivayisi afana nezithombe zedijithali njengesithombe, ngoba zingahlelelwa ukuthi ngaso sonke isikhathi x isikhathi, isithombe sishintsha ngaphandle kokwenza ngesandla.
Ifomethi yesithombe sedijithali
Enye yamafomethi asathuthuka asetshenziswa kakhulu yileso esisetshenziselwa izithombe zedijithali. Ekuqaleni, lezi zazicatshangelwa ukuthi zibonwe ngesikrini seselula, ikhompyutha noma ithelevishini, kepha ngokuhamba kwesikhathi abaningi nabo bafuna ukuba nalezi zithombe ephepheni.
Kulokhu, isilinganiso singu-4/3, okungukuthi, ububanzi buhlukaniswe baba izingxenye ezine ezilinganayo ngenkathi ukuphakama kuyizingxenye ezi-4.
Lapho uphrinta izithombe zedijithali, khumbula ukuthi ukuphakama kwesinqumo, kuba ngcono ikhwalithi yezithombe. Sikhuluma nge-300 dpi. Inkinga ukuthi lokhu kungasho isisindo esikhulu ezithombeni, okuthi, kwesinye isikhathi, singasekelwa ngamanye amadivayisi.
Osayizi bezithombe, bayini?
Uma ucabanga ngezithombe, into ejwayelekile ukuthi, noma ucabanga ngalezo onazo kuselula yakho, kodwa ngaphambi kokuba izithombe zibe nomzimba wenyama, futhi iningi lazo linosayizi ojwayelekile, 10x15cm, obekujwayelekile lapho bezizobathuthukisa.
Kepha uyazi ukuthi kukhona osayizi abaningi bezithombe? Lokhu ngokuyisisekelo kubhekise kumasentimitha abangawalinganisa, kokubili ngobude nangobude. Noma yisiphi isithombe "singaphrintwa" ngosayizi abahlukene, kusukela kokuncane kakhulu kuya kokukhulu kakhulu.
Zingaki osayizi bezithombe abakhona?
Ukuhlunga zonke osayizi bezithombe bekungeke kube yisicefe kuphela, kepha kube nezinxushunxushu eziphelele. Ekugcineni ubungeke wazi ngezinombolo eziningi kangaka futhi ungagcina ukhetha lezo ezizwakala njengawe ungazi ngempela ukuthi ihamba phambili yini noma cha.
Ngokuvamile, singakutshela lokho osayizi abajwayelekile nabasetshenziswa kakhulu Yilezi ezilandelayo:
- 4 × 4 cm (ikhadi)
- 9 x 13 cm
- 10 x 14 cm
- 10 x 15 cm (lokhu mhlawumbe kuvame kakhulu lapho kwenziwa izithombe, ngoba ngosayizi weposikhadi)
- 11 x 15 cm
- 11 x 17 cm
- 13 x 17 cm
- 13 x 18 cm
- 13 x 20 cm
- 15 x 20 cm
- 18 x 24 cm
- 18 x 26 cm
- 20 x 25 cm
- 20 x 27 cm
- 20 x 30 cm
- 22 x 30 cm
- 24 x 30 cm
- 30 x 40 cm
- 30 x 45 cm
Kodwa-ke, ngaphezu kwalawa masayizi kukhona okuningi, yize kwesinye isikhathi amaphrinta akhethekile adingekayo angenza imidwebo emikhulu.
Ingabe ukulungiswa nama-megapixels kuyalithinta ikhwalithi yezithombe?
Okunye kokwesaba okukhulu, ikakhulukazi eminyakeni embalwa edlule, ukuthi amakhamera anama-megapixels ambalwa athatha izithombe ezimbi kakhulu kunalezo ezinamanye. Kepha iqiniso ukuthi, yize kunempi ebikhona phakathi kwabakhiqizi, iqiniso yilokho ngisho nesinqumo esiphansi sikhiqize izithombe ezisezingeni eliphakeme, ngisho nokunweba.
Manje, lokhu akusho ukuthi ungathenga noma iyiphi ikhamera ye-megapixel ephansi noma iselula ukuthola izithombe ezisezingeni eliphakeme.
Okokuqala kufanele ucabangele ukuthi ukulungiswa kwekhamera, okuyisayizi isithombe esikwaziyo ukusithola. Isibonelo, uma ikhamera ithi 24MPx, kusho ukuthi sonke isithombe osithatha nayo sizoba namaphikseli ayizigidi ezingama-24. Ngakho-ke, lapho unakho okuningi, kungcono. Noma cha. Yilapho kusebenza khona amaseli enzwa inzwa. Lezi yizo ezinakekela ukuvuma amazinga wokukhanya angaphezulu noma amancane, ngaleyo ndlela zinikeze izithombe ezingcono.
Ubuphi ubukhulu bezithombe okufanele uziphrinte?
Ngokuya ngesinqumo sesithombe (esiboniswe ngamaphikseli) kanye nokulungiswa kwephrinta (okukhonjiswe ku-dpi), kukhona ifomula ekuvumela ukuthi wazi ukuthi yini ubukhulu besayizi bokuphrinta besithombe.
Ngokuvamile, okulungele umsebenzi wokuqhafaza ukuthi isithombe sinesisombululo se-300 dpi futhi, uma siyifomethi enkulu, singama-600 dpi. Amaphrinta esinawo ekhaya, amaphrinta we-inkjet, cishe ngaso sonke isikhathi anesinqumo se-300 dpi, esibenza bakwazi ukuphrinta izithombe.
Isibalo, ukuze wazi ukuthi ubukhulu bezithombe okufanele uziphrinte, yilokhu okulandelayo:
Ubude (cm) Ubukhulu obukhulu = 2,54 x inani lamachashazi (amaphikseli) / ukulungiswa kwe-dpi
Lokhu akusho ukuthi isithombe esikhudlwana asikwazi ukuphrintwa, kepha ikhwalithi yesithombe ingahle yehle. Futhi lokho kuyabonakala ngokubonakalayo, okuzokwenza ukuthi kubonakale kufiphele ngokwengeziwe noma nemibala ngeke ihlukaniswe kahle.
Ingabe izingqinamba zefomethi yentuthuko nosayizi wesithombe zicace kuwe?
